Answer 1

The two most important parts of war are logistics and communication.

All those box-line-phalynx formations of old were effective because it kept men together and orderly. Once that order breaks down, you lose. You have chaos, and you can’t give orders to scattered men running scared in the wrong direction.

So the answer is, you keep track of your troops and communicate effectively. That way, you can just say, ‘Our guys are over here, so shoot those guys over there.’
